Strap for Datejust 36 Rolesor Yellow Diamond / Jubilee / White

The lug width of the Rolex Datejust 36 116243-0063 is 20 millimetres. This is the internal distance between the two lugs of the case—the fundamental parameter for selecting a compatible strap. Precise measurement ensures a perfect fit without requiring any adjustments.

For the 116243-0063 two-tone in yellow gold and stainless steel, American alligator in cognac or dark brown is ideal: it amplifies the golden tone whilst maintaining formal elegance. Alternatively, vegetable-tanned calf offers natural ageing and fascinating patina, whilst premium shell cordovan delivers legendary tactile quality and stiffness that progressively softens over time.

The strap is replaced by extracting the spring bars from the lugs. Use a dedicated tool or springbar tool to gently compress the bar from one side, easing its removal. Insert the bar into the new strap, align it with the lugs, and compress until you hear a click. A straightforward operation, though on valuable watches it is advisable to entrust this to a professional watchmaker.

Yes, provided the lug width is precisely 20 millimetres. High-quality aftermarket straps—such as those crafted by Casati Milano—use the same standard Rolex bars and guarantee perfect mechanical compatibility. The construction quality and materials used determine the genuine difference from generic straps.

A quality natural leather strap, subject to moderate daily wear, typically lasts between 18 and 36 months before showing evident signs of wear (cracks, fraying). Duration depends on climate, frequency of use, and exposure to perspiration and humidity. Vegetable-tanned leather, if properly cared for, develops a fascinating patina throughout its lifespan. Casati Milano straps include an 18-month warranty against manufacturing defects.
